I loved the Grass Lake Co-Op preschool. My son just graduated after completing 2 years there. It's a wonderful preschool, with great values. I love the fact that you have the opportunity to be a parent assistant. That's what the co-op is all about. If you choose to be a parent assistant, the tuition is cheaper, and you get to be involved hands on in your childs education and preschool experience. Being a parent assistant, you will assist once or twice a month at the preschool. Even if you choose not to be an assisting parent, you will still have the chance to be involved. There are family fun nights, a christmas concert, field trips, and many other activites that you can be involved in. My son made lasting friendships with the students, and I made friends with the parents. Also, Miss Lissa, the teacher, is a warm and caring person who balances just the right amount of love, and discipline when it comes to her students. She's a wonderful teacher, full of patience, kindness, and fun. My son adored her, as do all of her students. If anyone has any other questions, feel free to ask.
